Abstract: CREEP CONTROL FOR A CONTINUOUSLY VARIABLE TRANSMISSION               ABSTRACT OF THE DISCLOSURE A continuously variable transmission has a fixed pulley piece and has a movable pulley piece which is supported for movement toward and away from the fixed pulley piece, the width of a groove between the pulley pieces being increased or decreased in order to increase or decrease the radius of rotation of a belt looped around a driving side pulley and a driven side pulley which include the fixed and movable pulley pieces to thereby vary a belt ratio.  A hydraulic clutch is engaged and disengaged under control of a clutch pressure in order to vary a driving force output by the continuously variable transmission, and a control arrangement controls the hydraulic clutch so that creep caused by slippage of the hydraulic clutch in a hold mode during a reverse gear operation of the continuously variable transmission is larger than creep caused by slippage of the hydraulic clutch in a hold mode during forward gear operation of the continuously variable transmission.

Title: Linear motor supporting apparatus for vehicles
IPC: B60L13/03
Filed: 1989-11-29
Abstract: ABSTRACT    The linear motor supporting apparatuses are mounted to the front and rear portion of each bogie of a vehicle to maintain the small distance between an on-board coil and a ground stator, the on-board coil and the ground stator together constituting the linear-induction motor.          The linear motor supporting apparatus incorporates a servo device which regulates the vertical position of the on-board coil according to the contour of the ground stator to keep the on-board-coil-to-ground-stator distance to a small predetermined value.  The servo device consists of a valve body, a valve box, and a servo device body.  The valve body is secured to a sensor member, which runs on and is kept in contact with the ground stator.  The valve box is secured to the on-board coil.  The servo device body is mounted through a spring to the bogie.  The ground stator has some laying errors and there are variations in its height.  When the sensor member during operation is lifted up due to height variations in the ground stator, the valve body moves up causing, through hydraulic pressure, the valve box to follow its upward motion.  This in turn causes the on-board coil, which is integral with the valve box, to move up thus keeping the distance between the on-board coil and the ground stator constant.

Title: Rotary machine
Inventor: SAKAI HIROZUMI
IPC: H02K23/00
Filed: 1990-01-15
Abstract: Abstract The present invention relates to a rotary machine.

Abstract: A system for storing cylindrical objects includes at least two article supporting pallets having mating projecting noses and oppositely disposed recesses. The pallets comprise at least upper deck boards for supporting the articles on the one hand and engaging a supporting surface such as a floor on the tops of risers or other vertically disposed restrainers on the other hand. The projecting noses and opposed recesses are preferably tapered for ease of alignment. The pallet is dimensioned so that the pallet has a width dimension approximating two and three quarters the diameter of a selected article, a length dimension approximating two diameters of the selected article and the nose projects approximately one half the diameter of the selected article. The system also encompasses the use of a series of pallet sizes, wherein each pallet differs from the other by about 15 percent in size, which permits the user to achieve optimal storage density for a broader range of diameters for such articles.

Title: Azlactone graft copolymers
Inventor: COLEMAN PATRICK L
IPC: C08F291/00
Filed: 1990-04-09
Abstract: Abstract of the Disclosure Graft copolymers and processes for the ??eparation thereof are provided.  The copolymers comprise a base polymer having grafted thereto a monomeric 2-alkenyl azlactone.  The surface properties of the graft copolymers can be modified by binding thereto nucleophilic reagents comprising further functional groups with desired properties.  Further, the amount of azlactone available at the surface of a graft copolymer for binding to such nucleophilic reagents can be controlled by selecting a surface against which the graft copolymer is formed.  The graft copolymers exhibit desirable thermoplastic, melt flow, and adhesion properties and are particularly useful for immobilizing proteins.  Methods of immunoassay based on the immobilization of proteins are also disclosed. Another utility of the graft copolymers involves the compatibilizing of immiscible polymer blends.

Abstract: Abstract of the Disclosure:         In a fault locating system for use in combination with a communication network of a hierarchy comprising a plurality of communication units which are divisible into a plurality of layers, each of the communication units produces, on occurrence of a fault, first, second, and third alarm signals Iu, Id, and Ou representative of interruption of an input signal from an upper communication unit, interruption of an input signal from a lower communication unit, and interruption of an output signal to an upper communication unit.  A pattern of the first through the third alarm signals Iu to Ou is extracted from three specific communication units and is monitored to locate the fault.  In order to locate multiple faults, the first through the third alarm signals are erased after a single fault is located to monitor whether or not alarm signals remain without an erasure.  Similar operation is repeated until no alarm signal remain.  The three specific communication units may be composed of a highest communication unit located at a highest layer in faulty communication units, a counterpart communication unit of the highest communication unit, and an upper communication unit of the counterpart communication unit.

IPC: G06F12/02
Filed: 1991-06-21
Abstract: ABSTRACT This patent concerns a method of managing computer programs in order to shadow the data in a storage memory device into a system memory device.  Some of the data being shadowed into the system memory device is copied into a memory cache by a cacheable method.  When determining if the data should be written into and shadowed to the shadow address range of the system memory device, the data copied into the memory cache is to be flushed. Or the write-in action is rendered disabled in such write-in to the memory cache.  This patent also concerns a device of a supervisory computer program, including one shadow processing device, one memory cache, and a flushing device.  When determining if the data should be written into the shadow address range for the shadow to the system memory device so that the data copied into the memory cache is to be flushed, or, by a disable device, when determining if the data should be written into the address range of the shadow to the system memory device, the write-in action (the write-in to the memory cache) is rendered disabled.
